The Kingdom of Hungary (Hungarian: Magyar Királyság), sometimes just Hungary, was a monarchy in Central Europe that existed for nearly a thousand years between 1000 and 1918. It came back during the Interwar period from 1920 to 1944 as a regency. It was created when Stephen I of Hungary was crowned in Esztergom in the year 1000. The first monarchy collapsed in 1918 because of the First World War, and the regency was liberated by the Soviet Union in 1944 during the end of the Second World War.
In the Middle Ages, the Kingdom of Hungary was one of the most powerful monarchies to exist, and had many wars with the Ottoman Empire, usually because of the Balkans. It had an important role in both World Wars.
